Localytics Firebase Push Notifications are not working on Xamarin Forms for Android

I've managed to get this working in the past, but its suddenly stopped working and I don't know what to check in order to get it working again. I am trying to get push notifications working using Firebase Cloud Messaging through Localytics. I am testing using the Localytics Rapid Push Notification Test module. The device pairs ok but when I send the notification nothing happens on the device.
1) I've regenerated my google-services.json file and pasted into the root of my folder.
2) I'm pretty sure my Android Manifest is fine:
<meta-data android:name="LOCALYTICS_APP_KEY" android:value="{HIDDEN FROM STACK OVERFLOW}" />
<activity android:name="com.localytics.android.PushTrackingActivity" android:exported="true" />
<receiver android:name="com.localytics.android.ReferralReceiver" android:exported="true">
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="{HIDDEN FROM STACK OVERFLOW}" />
</intent-filter>
</receiver>
3) My implementation of FirebaseInstanceIdService gets called ok as I can debug it:
[Service]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class MyFirebaseIIDService : FirebaseInstanceIdService
{
const string TAG = "MyFirebaseIIDService";
public override void OnTokenRefresh()
{
var refreshedToken = FirebaseInstanceId.Instance.Token;
Log.Debug(TAG, "Refreshed token: " + refreshedToken);
Localytics.PushRegistrationId = refreshedToken;
SendRegistrationToServer(refreshedToken);
}
void SendRegistrationToServer(string token)
{
// Add custom implementation, as needed.
}
}
4) My implementation of FirebaseMessagingService never ever gets called!
[Service]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
public class MyFirebaseMessagingService : FirebaseMessagingService
{
const string _tag = "MyFirebase";
public override void OnMessageReceived(RemoteMessage message)
{
Log.Debug(_tag, "Remote Message Received");
}
}
5) In my MainActivity I am calling Localytics.RegisterPush(); within the OnCreate() override.
Can someone please help? Thanks in advance!

Receive notification in chat with fcm

Hi there I'm building the chat app using firebase and I would like to push notification when a user send message to another user with FCM.
Any help please

add compile 'com.google.firebase:firebase-messaging:11.8.0' to your app/build.gradle file.
and below code to your AndroidManifest.xml
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIdService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
MyFirebaseMessagingService.java
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFMService";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Handle data payload of FCM messages.
Log.d(TAG, "FCM Message Id: " + remoteMessage.getMessageId());
Log.d(TAG, "FCM Notification Message: " +
remoteMessage.getNotification());
Log.d(TAG, "FCM Data Message: " + remoteMessage.getData());
}
}
MyFirebaseInstanceIdService.java
public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
private static final String FRIENDLY_ENGAGE_TOPIC = "friendly_engage";
/**
* The Application's current Instance ID token is no longer valid
* and thus a new one must be requested.
*/
#Override
public void onTokenRefresh() {
// If you need to handle the generation of a token, initially or
// after a refresh this is where you should do that.
String token = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "FCM Token: " + token);
// Once a token is generated, we subscribe to topic.
FirebaseMessaging.getInstance()
.subscribeToTopic(FRIENDLY_ENGAGE_TOPIC);
}
}
Hope this will help you

How to get (FCM) token in android studio?

It's my first time to use FCM, I created a new project in android studio, then I clicked on "tools" and I chose Firebase, I followed all the steps in this window
and I copied and pasted these blocks of code exactly in the same location as mentioned
here's my Java code
public class ZeftToken extends FirebaseInstanceIdService {
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d("zeft", "Refreshed token: " + refreshedToken);
}
}
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
This is my Manifest file:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".ZeftToken">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
</application>
When I run the application I don't get the token in the logcat and it's completely missing. I don't know what's wrong.

Update
extend FirebaseMessagingService
use onNewToken instead of onTokenRefresh
getToken() method is now deprecated
#Override
public void onNewToken(String token) {
Log.d(TAG, "Refreshed token: " + token);
// If you want to send messages to this application instance or
// manage this apps subscriptions on the server side, send the
// Instance ID token to your app server.
sendRegistrationToServer(token);
}
if you want to retrieve token in you activity
use the below code .getInstanceId() instead of .getToken() method
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this, new OnSuccessListener<InstanceIdResult>() {
#Override
public void onSuccess(InstanceIdResult instanceIdResult) {
String newToken = instanceIdResult.getToken();
Log.e("newToken",newToken);
}
});

I solved my solution with this function below;
public void savePushToken(){
if (!settings.hasData(Keys.pushTokenSaved) ){
FirebaseMessaging messaging = FirebaseMessaging.getInstance();
messaging.getToken().addOnSuccessListener(s -> {
Log.d("ON TOKEN",s);
pushToken = s;
JSONObject params = new JSONObject();
JSONObject info = new JSONObject();
try {
info.put("os","android");
info.put( "framework", "flutter");
info.put( "cihaz_bilgisi", new JSONObject());
params.put("token",pushToken);
params.put("device_info",info);
} catch (JSONException e) {
e.printStackTrace();
}
NetworkHelper.request(MyMethod.put, Links.savePushToken, params, false, false,
response->{
Log.d("PUSH_REQUEST",response.toString());
if (response.has("successful")||response.optString("message").contains("Integrity constraint violation: 1062 Duplicate entry")) {
settings.setBool(Keys.pushTokenSaved, true);
}
});
});
}
}

if everyting other good. (i hope you have json file provided by fcm service ? )
just move
FirebaseInstanceId.getInstance().getToken();
to for example your application or mainactivity
if u have error ( null pointer exception ) than you firebase not initialized. Check againe tutorial. And dont forget about google-json

Maybe you've already received the token in previous instance of app. The method onTokenRefresh only gets called when it is created or updated. It will not be executed in all app instances. Clear app data or uninstall app and run it again so that new token will be created and you can see it in the log.
Make sure to store the received token in shared preferences or database for future usage.

Reference Get started with Firebase
Cross check the file path of google-service.json as specified
Check the console for FCM token when you launch the app(Main Activity)

Fetch old notification from fcm Android

I am using FCM for notification and it is working good in all scenarios in Foreground and background. My problem is when I am logout from my application and another user send me message, I am not getting any notification as I am logout which is fine, but when I again login in my application I want to receive that old unread notification so how to do this any help would be appreciated following is the code I used
public class FirebaseIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
Context ctx = this;
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
try {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
} catch (Exception e) {
e.printStackTrace();
}
}
}
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
FirebaseDatabase.getInstance().setPersistenceEnabled(true);
Log.e("remote", remoteMessage.getData().get("type") + "");
Log.e("remoteMessage", remoteMessage.getData() + "");
Log.e("remoteMessagebody", remoteMessage.getData().get("body") + "");
// handling other data also according to my app which i am not mentioning
}
}
I have used this code for fetching old notification but didnot worked
FirebaseDatabase.getInstance().setPersistenceEnabled(true);
and in manifest
<service
android:name=".MyFirebaseMessagingService"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".FirebaseIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
and in gradle
compile 'com.google.firebase:firebase-messaging:9.2.1'

An FCM message has its own lifetime -- 4 weeks default, could be modified by setting time_to_live in your payload. After that time, the message would be discarded.
What you could do is implement that each notif is saved in a your Server DB, if it is not read yet and you detect that the user re-logs in, re-send them as push notifications, or simply retrieve them in your app and display them as notifications.

Migrating GCM to FirebaseCM: onMessageReceived() not called in foreground

I'm trying to migrate Android client app from Google Cloud Messaging to Firebase Cloud Messaging. I strictly followed an official tutorial, but didn't succeed - onMessageReceived() method is not called when app in foreground.
So here are code snippets that I touched.
build.gradle (project level)
dependencies {
//other stuff
classpath 'com.google.gms:google-services:3.0.0'
}
build.gradle (app level)
apply plugin: 'com.google.gms.google-services' //this line in the bottom
and
dependencies {
//other stuff here
compile 'com.google.firebase:firebase-messaging:9.0.0'
}
AndroidManifest.xml
<service android:name=".service.FirebaseService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
and
<service
android:name=".service.MyInstanceIDListenerService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
and
<service
android:name=".service.RegistrationIntentService"
android:exported="false" />
as childs of <application> tag.
MyInstanceIDListenerService.java
public class MyInstanceIDListenerService extends FirebaseInstanceIdService {
final String TAG = "Firebase instance id";
#Override
public void onTokenRefresh() {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
Intent intent = new Intent(RegistrationIntentServiceEvent.TOKEN);
intent.putExtra(RegistrationIntentServiceEvent.TOKEN, token);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
}
}
FirebaseService.java
public class FirebaseService extends FirebaseMessagingService {
//OtherStuff
#Override
public void onMessageReceived(RemoteMessage message){
String from = message.getFrom();
Map data = message.getData();
Log.d(TAG, "Message: " + from); //Never appears in logcat
//other stuff
}
}
RegistrationIntentService
public class RegistrationIntentService extends IntentService {
private static final String TAG = "RegIntentService";
public RegistrationIntentService() {
super(TAG);
}
#Override
protected void onHandleIntent(Intent intent) {
try {
synchronized (TAG) {
String token = FirebaseInstanceId.getInstance().getToken();
Log.i(TAG, "GCM Registration Token: " + token);//This works fine
//and shows this line - 12-19 17:59:33.295 3146-5386/ru.bpc.mobilebank.bpc I/RegIntentService: GCM Registration Token: *some_token*
sendRegistrationToServer(token);
}
} catch (Exception e) {
Log.d(TAG, "Failed to complete token refresh", e);
}
}
private void sendRegistrationToServer(String token) {
Intent intent = new Intent(RegistrationIntentServiceEvent.TOKEN);
intent.putExtra(RegistrationIntentServiceEvent.TOKEN, token);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
}
}
Please, tell if i did something wrong and why registrations seems to be done properly, but the onMessageReceived() method is never called even if the app is in foreground. Thanks in advance.
P.S. By the way, is adding SHA-1 keys in Firebase console necessary? maybe this could cause the problem? But Firebase says this action is optional.

if you are using FCM then you should replace this
<service android:name=".service.GcmService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
to
<service android:name=".service.FirebaseService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
your service not registered properly..
